STILL-FURNACE OR OTHER FLUE.

SPECIFICATION forming part of Letters Patent No. 517,404, dated March 2'7, 1894.

Application filed June 2,1893. erial No.476A18. (No model.)

To aZZ whom it may concern.-

Be it known that we, THoMAs W. CHAMBER- LAIN and EDWARD L. AGAN, citizens of the United States, residing at Wheelers Mill, in the county of Grayson and State of Kentucky, have invented certain new and useful Improvements in Still-Furnace or other Flues; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The special object of the invention is to so combine valves with a furnacethat the heat may be controlled and regulated, thereby preventing a copper still from burning or boiling over and enabling the operator to make one extra run each day, and rendering it unnecessary to draw the fire to make the still cool while it is being emptied and filled up.

Our valve is adapted for use on the furnaces of whisky or other stills and all kinds of fines for heating purposes.

Figure l of the drawings is a perspective view of a still-furnace provided with our invention; Fig. 2 a horizontal section thereof and Fig. 3 a vertical section on the dotted line 00 as of Fig. 2.

In the drawings, A represents the furnace with openings d in the top, B the still which is placed over the middle of the furnace, and C the outer casing between which and the still is left an annular space for the circulation of hot air around the still. In the bottom of this air-chamberD is ahole d communicating with the combustion chamber of the furnace and from it rises the inclined deflector E which extends up to the annular cover F. This causes the hot air to circulate around the still before it escapes through the outlet f in cover F.

G is the still-cover having a pipe g through which the vaporized products of distillation pass. Over the furnace holes d works the slide-valve H so as to open or close communication with the furnace chamber, and also with the waste pipe I, the hot air 'being thus allowed to enter chamber D to heat the still or up through the waste-pipe to cool it.

J is a slidevalve in the casing O which keeps out or lets in cold air to the chamber D, this valve and the valve H being connected by rods j h with the same lever is fulcrumed on a projection ifrom the waste pipe and operated together so that the valve J may be opened whenever the valve H closes the inner opening 01.

What we claim as new, and desire to protect by Letters Patent, is

The combination of the furnace A with the two openings at in the top, the superposed still B, the case 0 arranged around the still to form an intermediate chamber D communicating by one of the openings at with the furnace chamber, the waste pipe I communicating by the other opening at with the furnace chamber, the slide valve H covering the openings d at different times and the slide valve J adapted to cover or uncover an opening in the side of the case 0, the said valves being so connected by suitable mechanism with the same hand-lever whereby when there is a direct draft, the still is cooled; and when there is an indirect draft, the communication, between the chamber surrounding the still and the outer atmosphere, is closed by the valve J all substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
